[Q] Problem with External SD and CWM

I've had the Captivate for a couple of months now and am on xda reading everyday (my wife says I'm obsessed) -- I have yet to find the cause/solution for my problem. I've searched and found similar topics, but I'm not sure if they really apply to my issue.
This problem has followed me to a couple of different ROMs. I started with stock Eclair, Serendipity 5.xx, Cognition 4.1, stock Froyo, and then back to Cognition 4.1.1. I don't recall exactly when the issue started, but I think it was around Cog4.1/stock Froyo.
In Android, I can see it just fine as /sdcard/external_SD (normally use Linda manager). I can copy/move files to/from without any issues. If I plug the phone into the computer, I can access both internal and external SD cards with no problems.
Anyway, CWM 2.5.1.3 -Voodoo Lagfix will not see/mount my external SD card. Attempting to mount /sd-ext produces the error:
E:Can't mount /dev/block/mmcblk1p2 (*NOTE: I've seen posts with this message, but under slightly different circumstances)
(File Exists)
Error mounting SDEXT:!
If, however, I go to "choose zip from sdcard" and then navigate to "external_SD" it will "go" -- however this is **NOT** my external SD card, it appears to be a separate partition. My actual external SD has lots of folders and files, but the CWM "external_SD" has two files that I copied to it attempting to troubleshoot the issue.
A few minutes ago, within Android, I found that if I unmount my external SD, when I navigate to "external_SD", I don't see the files on my true external SD (as expected), but instead I see the partition with my two test files.
I apologize for this lengthy post, but I am at a loss and don't know what else to try. If this has been covered somewhere else, again, I apologize and would greatly appreciate pointing my in the right direction.
Thanks much!

how big is this partition?
**i think** somewhere along the road you clicked "partition sd card" in clockwork recovery.
use windows: Start> Administrative tools > "computer management" > "disk management" tree > edit/delete/expand/shrink partitions manually.

Checked partitions in Windows. The mystery "external_SD" wasn't a partition. it was a plain folder named external_SD (don't remember creating that folder, but probably did). I deleted the folder. I still get the same message in CWM.
When connected to the computer, the internal storage shows as FAT32, capacity 13.03GB (single partition); the external storage shows as FAT32, capacity 7.6GB (which is correct - also single partition).
Just for the record, this issue doesn't appear to be creating any stability or performance problems. I want to figure this out just because...
I appreciate the help thus far.

Anyone have any other ideas of how to get my external SD card to mount in CWM?

i have this trouble too on speedmod_k13c kernel.
i want to place and store all my roms and patches on external sd, but now I'm afraid to do it
maybe it's need to create folder with special name on internal SD (ext-sd for example), which will be point of mount.
unfortunately, CWM don't echo detailed information about error even

Flashing different ROMs can lead to this. It's always a good idea to remove your external SD when flashing.
Try dumping the contents of the card to your PC with a card adapter, then reformat using this:
http://panasonic.jp/support/global/cs/sd/download/sd_formatter20.html
Use the FULL (ERASE ON) setting and leave FORMAT SIZE ADJUSTMENT off.
When you put the files back on, only put the data, don't put any system settings etc back on.

Ok -- I will try this when I get home tonight.
Thanks,

Cyanogenmod 7 External Sd Card problem.

Hi all,
I have flash cyanogenmod 7 gingerbread relase from this Thread: http://forum.xda-developers.com/showthread.php?t=940095&highlight=external
Everytings is perfectly working. But my 8Gb external sd card is not detected. Anyone face with this problem ?
Thanks and best regards,

I might be wrong but have you read the Faqs on the rom .
no SD card .
jje

Hmm you are right.
But cyanogen say;
"What about sdcards?
internal = sdcard, external = emmc
Only internal can be shared over usb at the moment."
I download QTADB for windows and i can transfer my Music folders to emmc folder in my phone. Start Power AMP and power amp rescan folder is not detect my emmc folder.
How can i solve this problem ?

Hi Again,
Finally i solve the problem. And everything in my ext sd card is back. Problem is emmc folder (means external sd card in cyanogenmod 7) not permitted for write and read.
I use QtADB Terminal for editing the directorys permition.
Step 1: type "su"
Step 2: go to root directory. If you type "ls" and can you see "emmc" you are right position.
Step 3: "chmod 777 emmc" or "$chmod 777 emmc" (for write and read permitted.)
Step 4: Reboot the phone and everythings are back in External Sd Card in EMMC
And Windows detect 2 Storage Drive now. One of 6GB Internal Sd Card, One of 8GB External Sd Card. And i can use my Music player Power AMP.
Everythings perfect for me now. Cyanogen is great ROM but this permision problem should bu fixed. Because i spend three day for solve this problem.
Regards,

Hi, I hate to open up an old thread, but does anyone know if this works with the newer nightly builds? I'm having what seems to be the exact same problem... Also, when I go to settings > storage, it doesn't register the card there, and the mount sd card option is blanked out. I'm guessing that that's cause of the emmc thing, but shouldn't it register the extra storage space in the settings somewhere? at the moment, it looks like 16gb has just disappeared...
Also, I'd liketo change these permissions from the phone, using terminal emulator, if that's possible... But your steps don't seem to work for that one.

I am not seeing that behavior at all. Are you sure it is not a problem with your SD card?

are you sure you flashed from a froyo 2.2 build. I flashed from 2.2.1 a while back when I first flashed CM7 and I had the same issues with my external SD, not sure if this is still a pre-req but all the instructions still say to flash from 2.2 when first going to CM7. see link below: I also had scrambled video when booting CM7 coming from 2.2.1 so that is another indication something is wrong, just make sure you follow the steps to a T and know that flashing from 2.2.1 froyo is not the same as flashing from 2.2 froyo
http://forum.xda-developers.com/showthread.php?t=1061946
anyways, this could also be an issue that you just aren't sure where to look coming from a samsung rom to CM7. To view your external in CM7 you have to open file manager (astro or whatever you use) hit the home button (file manager route), click the emmc folder and it should be your external SD card. In samsung roms it's in the external_sd folder off the internal SD card.
when I mount my drives via computer both drives come up and they are both read/write so not sure what the guy a couple posts up was talking about, could have been an early bug or something not sure, anyways works fine in the latest nightly so i'm happy

i'm having the same issue.
EMMC not seen by non root explorers
the only way to acces the emmc is by using a root explorer...
LE: found a fix:
External SD card will get mounted as /mnt/emmc. This may not be visible to all apps. If you desperately need the contents visible to apps only looking in /mnt/sdcard, create an empty directory there and remount the /mnt/emmc there as well:
Using either the terminal emulator or adb shell:
su
mkdir -p /mnt/sdcard/external_sd
mount /dev/block/vold/179:9 /mnt/sdcard/external_sd

Click to collapse
Note: This is only a temporary fix for when needed. It will cause issues when you try to use USB sharing later. Write the following to get things back to normal:
umount /mnt/sdcard/external_sd

no /sdcard/external_sd
Just flashed to cyanogenmod7.1 found the same problem on my sgs2. ESFileExplorer shows the directory /sdcard/external_sd but it's empty (when I know it isn't).
If you go to settings > cyanogenmod settings > application the is a tick box "use internal storage"
Reboot, all files that were on the ext_sd are now mounted in /sdcard.
Haven't found a way of distinguishing which files are actually on the ext_sd and which are on the internal sd but they are all there.

cyanogen 7.1?

[Q] Recover files in internal sd while in Download Mode

my i9000m finally died and had the internal sd problem
made the usb jig and got into Download mode.
Now, how do i recover the files that i need on the internal sd ?

maybe recovering is a better way to put it
i don't really see any button in Odin that points towards recovering specific files in the internal sd

If the 3 button combi is working...then no problem....put it back in download mode again...and reflash the f/w thru ODIN...simple...

But the internal sd died
i get the:
E:Can't mount /dev/block/mmcblk0p1
(No such file or directory)
E:copy_dbdata_media:Can't mount SDCARD:
copy default media content failed

If the internal SD card died then you can't recover what's on it.
You could try a program called recuva and see what it finds but chances are slim.
Check the general section someone has made a work around for the SD failure. I can't post link I'm on mobile version

you're probably talking about this one:
http://forum.xda-developers.com/showthread.php?t=973687
but from what i gather. the internal sd is still off-limits.
i've flashed, JPU, and then JH2 and then DamianGTO STEAM kernel (Beta)
http://forum.xda-developers.com/showthread.php?t=901772
theres a couple format options, and theres a file manager. but nothing in there that appears i can access my internal sd card files

sd card problem

Shows up i.e. my computer when I plug in to the computer, shows up under settings/storage. But Astros and any other file manager doesn't show the as external card

Are you on 2.2 or 3.2?
On 3.2 the sdcard is sdcard2\
On 2.2 the sdcard is sdcard\

I am on 3.2, and I did see that the sd card was sd 2, although I can't figure out how to access it through astro or super manager

also, in cwm it is not finding the path to do a backup to the sd card

Under /mnt you will see /sdcard and /sdcard2.
If you are looking for sdcard2 from within the /sdcard directory, it's just an empty folder.
If you are looking at /mnt/sdcard2, that should hold the contents of your removable flash memory card.

What about in cwm, do I have to do anything to get it to read so I can backup my current ROM in case I would like to flash a custom in the future?

Save to the "sdcard" location and then transfer to "sdcard2" using a file explorer. I always archive my nandroids to a PC or a home server and only keep the most recent backup on removable storage.
Also, please be aware that doing a nandroids backup on a Honeycomb DS7 may not work out very well for you. Please read through the clockwork mod post found here:

[Q][HELP]Sd card not writable after fix on Kitkat 4.4.2

I'm having problems with the new sd card kitkat permissions, I have rooted my phone for that reason,I have applied the fix but nothing seems to make it work.
The sd card is readable, I am simply unable to write anything on it from my phone.
1. I am using a rooted device, no need to tell me a need a rooted phone.
2. I have used 2 different apps to modify the permissions file
3. platform.xml as been correctly modified
4. I am unable to copy files to the sd card from my computer when its in my Z1.
What is wrong with my phone and as this happened to anyone else ?

If you have 2 apps they may be causing conflicts
Please post a copy of your platform.xml

Here's a copy of my platform file.

That seems correct.
Try to create a file on your SD card using any explorer app that is not installed in system (i.e one you download from the play store)
If that works then the fix is working, it may be something to do with your PC

I can't create any files or any folder from ES file esplorer. I can't even create one fom file commander.

Try putting your sd card into your PC and seeing if you can create a file directly onto it that way

I'm able to create a file from a computer but only from an adapter, not directly in my phone.

I take it you mean that if you put your sdcard into a card reader or sdcard slot in our PC it works, but not when you are connectint the phone via usb cable
If so, what error does it give? Can you copy things off the card?

Yes I can copy things to my computer.
If I try to delete something off of it, it will act as if its deleted but when I remove it and plug it back its still there.

This is the exact same problem I have! Something happens to the cards as 1 out of 3 cards is perfectly fine but something you do with the phone ****s them up permanently I think.
